STANISLAW MROCZKOWSKI, OF NANTICOKE, PENNSYLVANIA.

AEROPLANE.

To all whoin it m (21 concern:

Be it known that I, STAMsLAw Mnocz- KOWSKI, a citizen of the United States of America, residing at Nanticoke, in the county of Luzcrne and State of Pennsylvania, have invented certain new and useful Improvements in Aeropla-nes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to aeroplanes, and has for its object to provide a vessel of such class, in a manner as hereinafter set forth with adjustable shields or curtains for protecting the engine, when the vessel is not in use and furthermore for protecting the aviator, as well as the engine, when the weather is inclement.

Further objects of the invention are to provide an aeroplane, which is comparatively simple in its construction and arrangement, strong, durable, provided with automatically closable protecting shields or curt-ains and comparatively inexpensive to manufacture.

\Vith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views :-F igure 1 is a side elevation of an aeroplane in accordance with this invention, Fig. 2 is a top plan and with the curtains rolled up, Fig. 3 is a front elevation illustrating the front curtain rolled up, Fig. 4 is a front elevation with the front curtain extended and furthermore detachably connected to one of the bars of the vessel frame, Fig. 5 is a longitudinal section, broken away, illustrating the curtains extended to shielding or protecting position, and Fig. 6 is a view illustrating one of the curtains extended, the curtain being broken away.

Referring to the drawings in detail, 7 denotes the main frame of the vessel which is provided at its top with an intermediate plane 8 of known construction and projecting from the frame 7, is a front frame 9, having attached thereto a front plane 10, of

known construction. Projecting rearwardly from the frame 7 is a rear frame 11, having connected thereto a rear plane 12 of known construction. The rear end of the frame 11 is provided with a rudder 13.

The frame 7, at its bottom, forwardly thereof, has depending therefrom a pair of brackets 14 and in each of which is mounted a wheel 15, the rear frame 11, at the back thereof has depending therefrom a pair of brackets 16, these latter extend toward each other and have mounted therein a wheel 17. The planes 8, 10 and 12, and rudder 13 are operated in a known manner and it is thought unnecessary to describe any operating elements therefor.

Mounted in the frame 7 is an engine 18, the shaft thereof being indicated at 19, and which is provided with a drive pulley 20, the latter being utilized for operating a pair of oppositely disposed belts 21, 22, which are mounted upon the pulley 20, as clearly illustrated in Fig. 1.

Secured to the front of the frame is a transversely extending member 23 of a length to project from each side of the frame 7 and each end of said member 23 is provided with a bearing 24, through which extends a propeller shaft 25, carrying on its forward end a propeller 26, and positioned forwardly with respect to the frame 7. Each propeller shaft is further mounted in a hearing 27, supported from the rear of the frame 7, and each propeller shaft 25 has its rear end formed with a pulley 28, the belts 21, 22, are mounted upon the pulleys 28. From the foregoing construction it is obvious that when the engine is operated, the propellers 26 will be actuated.

Mounted upon the front frame 9, at the rear of the plane 10, is,a transversely extending yoke-shaped member 29, the latter being fixed as at 30 to said front frame 9 and is of a length equal to the length of the plane 10. J ournaled in the member 29 is a spring actuated curtain roller 31 having connected thereto the lower end of a curtain 32. The upper end of the curtain 32 is provided with fastener members 33, for engagement with fastener members 84, which are carried by the forward top bar 35 of the frame 7. The members 33, 3 1, are utilized for fastening the curtain 32 to the bar 35 thereby maintaining the curtain 32 in an extended position. The curtain 32 is extended through the medium of a series of flexible pulling .n M. l

members 36, 37 and 38. The members 36 and 38 bcingattached to the ends ofthe curtain 32 and passing over pulleys 39 supported from the bar The member 37 is attached centrally of the curtain and passes over a pulley 40 carried by the bar 35. The free ends of the members 36,37 and 38 normally extend to a position where they can be grasped by the operator, so that the curtain 32 can be extended. Vhen the free ends of the members 36, 37 and 38 are made fast, the curtain 32 is held in an extended position. Each side edge of the curtain 32 is provided with a guide loop 41, which surround a stay 42 connected to the upper portion of the frame 7. The members 36 and 38 also pass through the front of the frame 7 as indicated in Fig. 3.

- Mounted upon the rear frame 11., at the forward portion of the rear plane 12 and fixed to said frame 11 is a yoke-shaped member 43, in which is journaled a spring controlled curtain roller 44, the latter having the lower end of a curtain 45 fixed thereto. The upper end of the curtain 45 is provided with fastener members 46, which are adapted to engage fastener members 47 carried by the rear top bar 48 of the frame 7, whereby the curtain 45 can be maintained in an extended position. The curtain 45 is elevated by a series of flexible pulling members in the same manner as the curtain 32. In Fig. 1, one of the flexible pulling members for the rear curtain 45 is indicated by the reference character 49. Stay bolts 50 are arranged at the rear of the frame 7 for the guide loops 51 of the curtain 45.

Boats 52, 53, are suspended from the frame and can be made of metal, canvas or rubber. The boats are conveniently shown in Fig. 1. Two will be carried at the forward end of the frame and one above the back Wheel.

VVhatI claim is I 1. Anaeroplane comprising a main frame, a front frame and a rear frame, planes carried by each of said frames, a rudder carried by the rear frame, an extensible spring controlled curtain carried by the front frame, means carried by the curtain and the main frame for maintaining the curtain in an extended position, a spring controlled extensible rear curtain carried by the rear frame, and means connected to the rear curtain and to the main frame for maintainin the rear curtain extended.

2. An aeroplane comprising a main frame, a front frame and a rear frame, planes carried by each of said frames, a rudder carried by the rear frame, an extensible spring controlled curtain carried by the front frame, means carried by the curtain and the main frame for maintaining the curtain in an extended position, a spring controlled extensible rear curtain carried by the rear frame, means connected to the rear curtain and to the main frame for maintaining the rear curtain extended, a series of flexible pulling members for elevating said front curtain, and' a series of flexible pulling members for elevating said rear curtain.

3. An aeroplane comprisinga mainframe, a front frame and a rear frame, planes carried by each of said frames, a rudder carried bythe rear frame, an extensible spring controlled curtain carried by the front frame, means carried by the curtain and the main frame for maintaining the curtain inan extended position, a spring controlled extensible rear curtain carried by the rear frame, means connected to the rear curtain and to the main frame for maintaining the rear curtain extended, and guiding means at. the sides of each of said curtains.

4. An aeroplane comprising a main frame,

a front frame and a rear frame, planes carried by each of said frames, a rudder carried by the rear frame, an extensible spring controlled curtain carried by the front frame, means carried by the curtain and the main frame for maintaining the curtain in an extended position, a spring controlled extensible rear curtain carried by the rear frame, means connected to the rear curtain and to the main frame for maintaining the rear curtain extended, a series of flexible pulling members for elevating said front curtain, a series of flexible pulling members for elevating said rear curtain, and guiding means at the sides of each of said curtains.

In testimony whereof I affix my signature in the presence of two witnesses.
